KNITTING-MACHINE.

Patented Nov. 1G. 1920.

Application filed February 9,1915. Serial No. 7.111.

To all whom 'it may concern Be it known that I. Emmi: U. Ames, o citizen of the United States, residingl in Philudel hie, Pennsylvanie, have invented certain Imitting-llnchines, of which the fol lowing is a specification.

My invention'consists of improvements in knitting machines and is particularly designed for producing/ seamless tubular knitted fabrics such as socks and stockings.

One object of the invention is to provide a durable pructicollv noiseless machine of comparatively -simple construction which will perform its work with a, minimum of attention from the operator, it being also desired to so make certain of the parts that they may he easily and accurately adjusted to effect a change in the character of the fahric made or to compensate for their Wear. A further object of the invention is to provide :i knittingmachine with mechanism which will produce a. change in the size of the stitches nt predetermined portions of the fabric so that ii reinforcing thread may be interknit therewith, the, invention contemplating an arrangement of parts whereby changes in the character of fabric may be produced without unduly straining or otherwise injuring the yarn.

The above objects and other advantageous ends I attain as hereinafter set forth. reference being had to the accompanying drewings, in which,

Figures 1 and 2 are respectively front and side elevations of a circular stoclringdinitting machine made in accordance with my invention;

Figs. 3 and 4 are e side elevation and a plan onen enlarged scale illustrating certain parts of the machine shown in Figs. l and 2;

Fig. 5 is a sectional elevation taken on the line fz-o, Fig. 4;

Figs. 6 and 7 are developed elevations showing certain needle and sinker cams respectivel)7 in positions occupied during the 'fr ielfcinf.;r of the heel or toe of :i stocking;

Figs. 8 und 9 are enlarged fragmentary elevations further illustrating the operation of certain of the knitting elements;

Figs. 10 and 1l aresections 'respectively taken on the lines f-f, Fig. 8 und f7-"0. Fig. 9;

Figs. 12 and 13 are plans showing the needles und suikers respectively in the positions shown in Figs. t5 and 9;

Fig. 14 is n dingrznnniatic view showing: adevelopeinent of n modified forni of the sinker com which may he used in connection with my invention.

In the above drawings, 1 is :i freine sul porting n needle cylinder' 2 which. dui-ing the operation of the machine. alternately receives e. rotary :1nd :in oscillatory movement from suitable driving mechanism 1:2 und is of any suitable construction having grooves 3 for the reception oi' needles Si.

The upper portion of the needle cyiinder has fixed to it .1 sinker ringr 13 for the ception of sinkels or weh holders l5 which are normally held in definite positions rohr tively thereto hy means of :i coil spring);` lo and have their ends 1i pivoted in :t groove 2 in said cylinder. The actuating :,ii'nis VlT ofthe sinkols extend within :l sinlicr com ring 18 surrounding the sinlcer ringr :1nd e. sinker cani 19 is n'ionnted on said ring' so as to engage the upper portions ol' suie? .irnis The actuating surface of this com is such (see Figs. 6 and 7) that when in one position, its end 19" will depress the arms 1T, causing the sinkers to assume n weve form-.ition and to be retracted from the needles. 0n the other hand, when said sinker cani l!) is moved into the position sh'own in Fig. T. the sinkers will he depressed. liv the end i9" of seid com, whose central surf-ico 19"' is substantially plone so that when either end of the cam is moved into cngngemc-rnt with the end portions 17 of the sinkei's to form en abrupt angular port of the wave thereof. said surface will cause :i grado-.rl angular depression of the sinlrers engaging;- it. This feature forms n very importent p-irt of my invention and will be again referred to in the operation of the machine.

The cam 19 is connected to the sinker com ring 18 by :i pivot pin 20 and has :i depending,t arm Q1. extending between two screivs 22 and Q3 adjustable in lugs 2i und 25. These project from :1 sleeve 26 secured to e. vertical post 2T so th-.it when the c vliiider 2 rotates in one direction. the sinkers turn with it und tho friction heivfecn tlwni. the sinker cem ring. und the needle ovlinder will more said ring.r in the saine direction iin-- til the arm 21 engages one of the adjusting screws 22 or Q3. Thereafter the sinltcr com wiring.
